thought id put together a thread that answered all those questions that most people are asking about strut swaps and what not

Small Datsun struts

1200 coupe/early 120y struts
bolt straight in to any 120y or 1200
No track increase
212x9.5mm solid disc and single piston calliper

Late 120y struts
also bolt straight into any 1200 or 120y
No track increase
219x9.6mm solid disc single piston caliper

Upgrades
s13 rotor and calipers with custom caliper bracket (link to wiki anyone?)


Larger Datsun struts

What you will need to make them bolt straight in:
This applies to all the struts listed below

Strut Top and Upper Spring Perch
-Standard 1200 ones

Lower Control Arms
-Stanza (A10), Sunny (B310), Late 1200 Ute or Late 120y

Castor rods
-Late 1200 Ute or Late 120y

Ball joints, Steering arms, Outer Tie rod Ends, Tie rods
-Stanza or Sunny

FOR R31 type struts, you will also need a sheer load spacer ring available from datsport
FOR all larger struts other than Stanza and sunny you will need to cut the spring perches off and run 1200 sized ones, or run coilovers.

Types of large struts


#1
Sunny
Early Stanza
180b
Early 240k

All have the same caliper bolt spacing and offset, sunny and maybe early stanza have smaller stub axles so hubs wont interchange between the bigger models.
most noticable different between these struts in the differing length strut tubes and different size spring perches
stanza and sunny have long strut tubes (not good for lowering a car) and small spring perches, like 1200s and 120ys
180b and early 240k both have the larger spring perches, and shorter strut tubes that stanza and sunny, also think 240k has slightly shorter strut tube than 180b....but unsure on measurements

Caliper Bolt Spacing is 3 inches/76.2mm
Commodore calipers and Volvo calipers will fit on these

A12 Sunny: 219x9.6mm solid disc single piston caliper
A14/15 Sunny: 245x10mm solid disc single piston caliper
180b: 245x10mm solid disc single piston caliper
Early 240k: 232x10 mm disc single piston caliper

Brake Upgrades

180b and 240k struts
Caliper: Commodore, VL(turbo or V8), VN/VP (V8), VR/VS(All Models)
Disc: Mitsubishi Magna DBA425 276x24mm vented

Mods to fit:
Machine the centre of the magna disc out to 73mm and drill 4 new holes to bolt to the Datsun hub
Add a 1.5mm spacer between the strut and caliper to centre the caliper on the disc
More info in this OZDAT thread

Or if you want to spend money and have someone else make it even more bolt, MADDAT sell this same setup


#2
Late Stanza
Small offset 200b
Small offset 240k

All struts have 3.5 inch/88.9mm caliper bolt spacing and same stub axles. 200b and 240k struts are identical; stanza struts have a longer strut body and smaller spring perch. Therefore 200b and 240k calipers are preferable as they allow more suspention travel

Calipers that will bolt on
Toyota Landcruiser caliper up to 75 series:
4-piston cast iron caliper suits 18mm vented disc

Toyota Hi-lux calipers various models
4-piston cast iron caliper, to suit 12.7mm solid disc or 20mm vented disc or 25mm vented disc depending on the model

Sumitomo caliper
As found on 240k, 240z, Corona, Gemini
Cast Iron Twin piston caliper to suit a 12.7mm solid disc

Early BMW 4 piston cast iron calipers

Holden Kingswood calipers
Single piston, suit a 25.4mm vented disc


Brake Upgrades

Caliper: Toyota Landcruiser 60 or 75 series caliper
Disc: S13 CA equip Silvia DBA918 250x18mm vented

Mods to fit:
Machine the inner bore of the disc out to 73mm, drill 4 new holes so that it can bolt to the Datsun hub
Clearance the caliper so that it doesn’t rub on the disc
(link to pics)

Caliper: Sumitomo Twin piston, from 240z, 240k, corona or Gemini
Disc: 200b or 240k DBA315 253x12.7mm solid disc
Straight bolt on to above struts

Theres also info on using BMW calipers in this ozdat thread

And in this Ozdat link it apparenlty tells you about fitting RX7 calipers and a 280x22mm disc

or if you have the money MADDAT make a couple of brake setups to bolt straight on, similar to the above RX7 caliper one

#3
Large offset 200b
Lage offset 240k

All the same specs as the Small offset 240k and 200b struts, except the caliper mounting ears are located further away from the stub axle. This allows a larger diameter disc to be used
Come standard with 270mm disc compared to small offset having 253mm

All the same calipers can be bolted on

Brake Upgrades
Caliper: Hi-Lux 4 piston caliper that suits 25mm disc
Disc: Mitsubishi Magna DBA425 276x24mm vented
theres more info on ozdat somewhere...but cant seem to find it


#4
R31
R30
910 Bluebird
S12 Silvia
280zx
Z31 300zx

NOTE: i havent actually had any experience with z31 or 280zx struts so the info below is just from what i have been told.
All have 3.5inch/88.9mm caliper spacing, but unlike the stanza, 200b, 240k struts the caliper mounts to the disc side of the strut. Therefore there is no thread in the strut mounts, its in the calipers instead
All the stock brakes are interchangeable between these 5 struts

Various different strut tube lengths with the z31 and 280zx struts being the shortest
Also the r31 struts and possibly others have a different stub axle angle to the other large Datsun struts. This gives you more wheel clearance to the strut tube and less negative camber
Bluebird struts on the other hand have the same stub axle angle as the other larger Datsun struts, allowing more negative camber and the same wheel fitment and 200b and 180b type struts.
Bluebird, 280zx and S12 have separate hub/disc arrangement like most of the other Datsun stuff. Whereas R31, R30 and z31 have an integral hub/disc setup

All but the bluebirds come stock with 250mm vented discs with thicknesses from 18mm-22mm

Brake Upgrades
As R31 brakes are the most evolved of all the stock brakes on these struts they are an upgrade for all that others

Or there is this Ozdat thread on fitting rx7 calipers

Also if you have the money there is the DATSPORT R32/R33 disc and caliper upgrade


Other Random Info

There are only 3 different types of hubs for the larger strut types, they are:
-Early Sunny and Early Stanza type
-Lat Sunny, Late, Stanza, 180b, 200b, 240k Type
-S12, 280zx and Bluebird Type

The last 2 share the same wheel bearings so are therefore interchangable between struts
but they do have different wheel mounting offset and different disc mounting offset to each other

Adjustable Control arms and Castor rods, so you know what they are

Twin piston sumitomo calipers on stanza struts

Awesome idea mate, Very helpful. Be stuffed without blokes like you and Tommo73 amongst many others.

+1

Just on the early/late thingo... I think it is more aussie assembled and jap assembled thing.

My 1979 stanza (square headlight) has the girlock calipers, b/w rear end with girlock drums and wheel cylinders and b/w auto transmission. But my old stanza was a round headlight job with jap calipers and H165 but that was 1980.

Oh and 280zx, same hub setup as a stanza etc. disc bolts to hub.

280zx and S2 Z31 are shorter than R31.

same as in non integral hub? guess they are the same hub as bb and s12 then

and yeah the early and late thing, jap ones were made first...therefore they can stay are early ones :-p

youve changed brakes like ive changed wheels lol

if any one knows its you gtr brake king

Yep the hub is seperate from the disc. The disc bolts to the rear of the hub.

and yeah, stanza's...

but the hug is alot thinner between where the disc bolts on and where the wheel bolts than a stanza or 200b hub?

and early and late stanzaz...doesnt really matter either way as they are both crappy struts

Like this




Yeah and stanza's just suck generally.
